Abstract:
Studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of standardized method of patch test.However, most previous epidemiologic reports studied patients with allergic contact dermatitis in hospitals with patcb testing. Such data are not directly applicable to the population at large. Very recentiy there are a few reports ahout rates of exposure and patch test reactivity to certain antigens in a general population. which is difficult to be applicable in a developing country at present. With regard to this, we have tried to analyze the contact dermatitis questionaire containing various items of common causative agents producting contact dermatitis (for example, metals, cosmetics, plants, medicaments and rubber etc.) for the detection of past contact dermatitis histories in a total new dermatologic outpatients. A11 2258 dermatologic outpatients entered this study including 303 contact dermatitis patients (allergic contact dermatitis, primary irritant dermatitis and housewife eczema). We also analyzed the patch test results of 107 patients with suggesting contact dermatitis who visited our hospital at the same period of collecting questionaires. The study results were as follows. 1. Positive rate of each item of the questionaire (No. of said Yes/ No. of responders) was metals, 10.4% cosmetics, 31.8%, plants, 18.2%; medicaments, 12.4%; rubber, 5.8%; and others, 11.7%. 2. The most common all regens of the patch test positive reactions were nickel sulfate (9.3%), fragrance mix(9.3%), formaldehyde(6.5%), potassium dichromate (5.6%), neomycin sulfate (5.6%), balsam of Peru (4.7%), cobalt chloride(3.7%), wood tar(3.7%) and paraphenylene diamine (2.8%) in order of frequency. And the patch test positive rate of commercial cosmetic products was 10.3%. In conclusion, cosmetics, medicaments, metals, plants and rarely rubber are found the most common etiologic agents of contact dermatitis in this study. The reasons and back-ground of the results were also discussed in various aspects.
